G Sound lower than tuning note ¡ Tune the instrument by tightening all tuning bolts by an equal amount (max. 1/16 of a turn). G Sound higher than tuning note ¡ Tune the instrument by loosening all tuning bolts by an equal amount (max. 1/16 of a turn) according to the procedure described in step 3. 8 Operate the pedal as described in step 5. If the pitch does not change, the instrument is tuned properly. (If the pitch changes, repeat from step 7.) The instrument is now tuned to the lowest sound (note) of its tonal range. Depress the toe of the pedal to change to a higher pitch (note). 9 After tuning, perform x Pedal Adjustment and then c Tuning Indicator Adjustment. x Pedal Adjustment After depressing the toe and heel of the pedal, turn the spring tension adjustment bolt as described below.

Do not turn by too many full rotations at once, but re-check the adjustment state every 2 turns by depressing the toe and heel of the pedal. Note Do not loosen the spring tension adjustment bolt by more 3 rotations at a time, as the toe of the pedal tends to drop abruptly after a specific point. Caution Never put your hands etc. under the pedal. Spring tension adjustment bolt Spring Timpani key G Pedal balance spring mechanism Your Yamaha pedal timpani is equipped with a unique pedal balance spring mechanism (a coil spring counteracting the tension of the head) which allows you to freely change the pitch (note) of the instrument at an instant. When the pedals are moved, the pitch of the head will change, and the balance spring ensures that the pedal angle (pitch) will not change when you remove your foot from the pedal. 7
